I understand and agree -- let's talk only about multi-resolution compositing preview discrepancies for now and remove render-percentage and scene-render-resolution. I can do the coding, if I can only understand what is broken! :) Perhaps later I can look at render-percentage. When multiple resolution inputs are involved (even all images, no 3d render), I'm seeing the following issues... 1) The composite-node preview-thumbnail does not match the F12-render output 2) No way to backdrop something that matches F12-render-output, because a viewer sees the data uncropped by render-resolution. 3) discrepancies between the preview node-thumbnails and final-render node-output, due to differences in cropping and centering during preview vs final.. Here is a screenshot which I think will help this discussion... http://www.pasteall.org/pic/54391 This shows issue #1, where none of the node-previews actually look like the F12-render output. Is it safe to change only the composite node thumbnail to always match the F12-render output? Well, kind of yes. At least in case viewer is connected to the same node as > Composite Output.

I think it's confusing for the viewer to behave differently based on whether or not composite output is connected to the same output. However, it is desirable to be able to have a backdrop which matches F12-render. Here are two ideas, do you like either of them? (a) make the composite node also a "viewer", in that you could click on it and have the backdrop pull from it. (this backdrop should 100% match f12-render output) (b) give the composite node an "output", which could be hooked to a viewer to backdrop the composite/f12-rendered output. I prefer "a", because it seems strange to me that the composite node can't be a backdrop, and because it seems simpler. However, either seem fine. Any reason not to do one of these? ..... on to #3... Here is a screenshot... http://www.pasteall.org/pic/54401 In this screenshot you can see another discrepancy. The add and mix nodes have the same inputs, but their thumbnails are not the same size or aspect ratio. Swapping the inputs on both nodes changes their thumbnail size/aspect-ratio but they still don't match. Is there any reason for this to be the case? _______________________________________________ Bf-committers mailing list [email protected] http://lists.blender.org/mailman/listinfo/bf-committers
